CentOS 7 : rsync (RHSA-2022:6170)

high Nessus Plugin ID 164624

Language:

Synopsis

The remote CentOS Linux host is missing a security update.

Description

The remote CentOS Linux 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:6170 advisory.

 - An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file). (CVE-2022-29154)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected rsync package.
